Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, and in particular to an organic fertilizer granulation device. Background Technology

[0002] Organic fertilizer, primarily derived from plants and / or animals, is a carbon-containing material applied to the soil to provide nutrients to plants. It is processed from biological matter, animal and plant waste, and plant residues, eliminating toxic and harmful substances and enriching it with beneficial substances, including various organic acids, peptides, and abundant nutrients such as nitrogen, phosphorus, and potassium. It not only provides comprehensive nutrition for crops but also has a long-lasting effect, increasing and renewing soil organic matter, promoting microbial reproduction, and improving the soil's physical, chemical, and biological properties. It is a key nutrient source for green food production. In the production process of bio-organic fertilizer, granulation equipment is typically used to produce granules, making it easier for the fertilizer to be absorbed.

[0003] For example, Chinese utility model patent CN219559537U provides an organic fertilizer granulation device, including a frame, a main body on the frame with a granulation chamber, an end cap at one end of the main body, the end cap having at least two granulation zones, each granulation zone having a granulation hole penetrating the end cap, the diameters of the granulation holes in the at least two granulation zones being different, and also including a feeding assembly and an adjusting assembly. The feeding assembly includes a transmission rod rotatably disposed in the granulation chamber, the outer peripheral wall of the transmission rod having a spiral blade, and the adjusting assembly includes a cover plate rotatably disposed on the end cap, the cover plate having a slot for exposing at least one granulation zone, the diameters of the granulation holes in the granulation zones exposed in the slot being equal.

[0004] Although the above-mentioned device solves the technical problem that existing organic fertilizer granulators cannot adjust the particle size of the produced organic fertilizer granules according to production needs, the device directly puts the organic fertilizer into the granulation chamber for granulation. However, the impurities such as stones, tiles, and glass fragments contained in the fermented organic fertilizer cannot be completely removed, resulting in impure organic granulated fertilizer and reducing the granulation effect of organic fertilizer. Utility Model Content

[0005] This utility model discloses an organic fertilizer granulation device, which solves the problem that in the process of using traditional organic fertilizer granulators, organic fertilizer is directly put into the granulation chamber for granulation, but the impurities such as stones, tiles, and glass fragments contained in the fermented organic fertilizer cannot be cleaned, resulting in impure organic granulated fertilizer and reducing the granulation effect of organic fertilizer.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An organic fertilizer granulation device includes a horizontally arranged cylindrical granulation chamber. A drive shaft is coaxially arranged inside the granulation chamber. A second motor is located on the outside of the granulation chamber to drive the drive shaft to rotate around its own axis. A spiral blade is fixed on the drive shaft. The top of the granulation chamber is connected to a screening chamber with a vertical cylindrical structure. The top of the screening chamber is connected to a feed funnel. A stirring shaft is coaxially arranged inside the screening chamber. A first motor is located on the screening chamber to drive the stirring shaft to rotate around its own axis. A stirring paddle is fixed on the stirring shaft. A sieve plate is fixed at the bottom of the screening chamber to separate the granulation chamber and the screening chamber. A rotating rod is fixed at the bottom of the stirring shaft to fit against the top surface of the sieve plate. A vertically arranged scraper is fixed at one end of the rotating rod and fits against the inner wall of the screening chamber. An opening is opened on the side wall of the screening chamber. An electrically controlled valve is located on the outside of the screening chamber to block the opening. A waste tray is fixed inside the opening. A granulation plate is fixed at the end of the drive shaft and rotates coaxially with the drive shaft.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The organic fertilizer to be granulated is poured into the screening chamber through the feed hopper. As the first motor starts, the stirring paddle continuously agitates the organic fertilizer, ensuring it is evenly dispersed. Because a screen plate is fixed at the bottom of the screening chamber, the organic fertilizer falls from the screening chamber into the granulation chamber by its own gravity, allowing impurities such as stones, tiles, and glass fragments to be screened out. The rotating rod facilitates the falling of the organic fertilizer and prevents it from remaining on the screen plate. The scraper prevents the organic fertilizer from sticking to the inner wall of the screening chamber, avoiding material loss and waste. The organic fertilizer falling into the granulation chamber is conveyed by the spiral blades, passes through the granulation plate, and is compressed into granules, thus producing organic fertilizer pellets. When all the organic fertilizer in the screening chamber has been discharged, the electrically controlled valve is activated. As the rotating rod rotates, the stones, tiles, glass fragments, and other impurities in the organic fertilizer are discharged from the opening onto the waste tray, thus entering the external container. This invention combines screening and granulation, which can screen out impurities such as stones, tiles, and glass fragments contained in organic fertilizer, while avoiding material loss and waste, effectively improving the purity of the final product, and thus improving the efficiency of the entire granulation device.

Detailed Implementation

[0015] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 and Figure 2 As shown, this utility model provides an organic fertilizer granulation device, including a horizontally arranged cylindrical granulation chamber 1. A drive shaft 6 is coaxially arranged inside the granulation chamber 1. A second motor 61 is provided on the outside of the granulation chamber 1 to drive the drive shaft 6 to rotate around its own axis. A spiral blade 62 is fixed on the drive shaft 6. A screening chamber 2 with a vertical cylindrical structure is connected to the top of the beginning of the granulation chamber 1. A feed funnel 21 is connected to the top of the screening chamber 2. A stirring shaft 4 is coaxially arranged inside the screening chamber 2. A first motor 41 is provided on the screening chamber 2 to drive the stirring shaft 4 to rotate around its own axis. A stirring paddle 42 is fixed on the shaft 4. A sieve plate 5 is fixed at the bottom of the screening chamber 2, which separates the granulation chamber 1 and the screening chamber 2. A rotating rod 43 is fixed at the bottom of the stirring shaft 4, which is in contact with the top surface of the sieve plate 5. A vertically arranged scraper 44 is fixed at one end of the rotating rod 43. The scraper 44 is in contact with the inner wall of the screening chamber 2. An opening 22 is opened on the side wall of the screening chamber 2. An electrically controlled valve 23 is provided on the outside of the screening chamber 2 to block the opening 22. A waste material tray 24 is fixed inside the opening 22. A granulation plate 7 is fixed at the end of the drive shaft 6. The granulation plate 7 rotates coaxially with the drive shaft 6.

[0017] like Figure 1As shown, a drying chamber 3 is connected to the granulation chamber 1 near its end. A granulation plate 7 separates the drying chamber 3 from the granulation chamber 1. A conveyor belt 31 is installed inside the drying chamber 3. A drive motor 32 for driving the conveyor belt 31 is fixed at the bottom of the drying chamber 3. A heating box 8 for heating the drying chamber 3 is installed at the top of the drying chamber 3. A discharge pipe 33 is connected to the side of the drying chamber 3 away from the granulation chamber 1. When the organic fertilizer in the granulation chamber 1 is conveyed by the spiral blades 62 and passed through the granulation plate 7, it is extruded into granules. The granulated organic fertilizer falls onto the conveyor belt 31 inside the drying chamber 3. Since the heating box 8 is installed at the top of the drying chamber 3 to heat the drying chamber 3, the organic fertilizer on the conveyor belt 31 can be dried. After being conveyed by the conveyor belt 31, it is discharged through the discharge pipe 33 and enters an external container to obtain the final product.

[0018] like Figure 1 As shown, a fan 82 is fixed inside the heating box 8, and an air inlet 81 is connected to the top of the heating box 8. A heating strip 83 located at the bottom of the fan 82 is fixed inside the heating box 8. Several ventilation holes 9 connected to the heating box 8 are opened on the top of the drying chamber 3. The fan 82 introduces air into the heating box 8 through the air inlet 81 and then exhausts it into the drying chamber 3 through the ventilation holes 9. Since the heating strip 83 is fixed inside the heating box 8, the heat from the heating strip 83 can be blown into the drying chamber 3, thus heating and drying the organic fertilizer on the conveyor belt 31.

[0019] like Figure 3 As shown, a filter plate 92 is fixed to one end of the ventilation hole 9 near the drying chamber 3, and a fan blade 91 is rotatably connected to the side of the filter plate 92 near the heating box 8. The filter plate 92 can prevent organic fertilizer from entering the heating box 8 and causing blockage of the ventilation hole 9; the fan blade 91 in the ventilation hole 9 can rotate to speed up the transfer efficiency of hot air, so that the organic fertilizer in the drying chamber 3 is quickly dried during the conveying process.

[0020] like Figure 1 and Figure 4As shown, vertically arranged blades 71 are fixed on the top inner wall of the drying chamber 3. The blades 71 are in contact with the side of the granulation plate 7 closest to the drying chamber 3. An inclined guide plate 72 is fixed to the bottom of the blades 71. The width of the guide plate 72 is greater than the width of the blades 71. The bottom end of the guide plate 72 contacts the top surface of the conveyor belt 31. One end of the discharge pipe 33 corresponds to the end of the conveyor belt 31. When the organic fertilizer in the granulation chamber 1 is conveyed through the granulation plate 7 by the spiral blades 62, the organic fertilizer can be cut evenly and produced into organic fertilizer granules of the same size because the granulation plate 7 rotates coaxially with the drive shaft 6 and the blades 71 are fixed. Since the width of the guide plate 72 is greater than the width of the blades 71, the cut organic fertilizer can fall onto the inclined guide plate 72 and be discharged onto the conveyor belt 31. The fact that one end of the discharge pipe 33 corresponds to the end of the conveyor belt 31 effectively prevents the organic fertilizer from falling off the conveyor belt 31 during discharge, avoiding material loss and waste.

[0021] like Figure 1 As shown, the waste tray 24 is inclined, and the top surface of the waste tray 24 is flush with the top surface of the screen plate 5. The inclined arrangement of the waste tray 24 facilitates the discharge of debris such as stones, tiles, and glass shards from the organic fertilizer into the screening chamber 2.

[0022] like Figure 1 As shown, a support 11 is fixed at the bottom of the granulation chamber 1. The support 11 can support the entire device.

[0023] In use, the organic fertilizer to be granulated is poured into the screening chamber 2 through the feed funnel 21. With the start of the first motor 41, the stirring paddle 42 continuously agitates the organic fertilizer. Since the bottom of the screening chamber 2 is fixed with a screen plate 5, the organic fertilizer can fall from the screening chamber 2 into the granulation chamber 1 by its own gravity, allowing impurities such as stones, tiles, and glass fragments to be screened out. Simultaneously, the rotating rod 43 facilitates the discharge of the organic fertilizer and prevents it from remaining on the screen plate 5. The scraper 44 prevents the organic fertilizer from sticking to the inner wall of the screening chamber 2, avoiding material loss and waste. The organic fertilizer falling into the granulation chamber 1 is conveyed by the spiral blades 62, passes through the granulation plate 7, and is then extruded into granules. Because the granulation plate 7 rotates coaxially with the drive shaft 6 and the blades 71 remain stationary, the organic fertilizer can be cut evenly to produce organic fertilizer granules of the same size. The organic fertilizer is discharged onto the conveyor belt 31 by the inclined guide plate 72. The fan 82 in the heating box 8 introduces air into the heating box 8 through the air inlet 81 and then discharges it into the drying chamber 3 through the ventilation hole 9. Since the heating box 8 is equipped with heating strips 83, the heat from the heating strips 83 can be blown into the drying chamber 3, thus heating and drying the organic fertilizer on the conveyor belt 31. The dried organic fertilizer is discharged through the discharge pipe 33 to obtain the final product. When all the organic fertilizer in the screening chamber 2 has been discharged, the electric control valve 23 is activated. As the rotating rod 43 rotates, the stones, tiles, glass fragments and other impurities in the organic fertilizer can be discharged from the opening 22 onto the waste tray 24. This can screen out the stones, tiles, glass fragments and other impurities contained in the organic fertilizer, effectively improving the purity of the final product and thus improving the efficiency of the entire granulation device.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
